Definitions
- a surge arrester is a protective device designed primarily for connection in parallel with an electronic device to bypass a transient overvoltage when occurring in the electronic device, thereby protecting the electronic device from being damaged due to a sudden overvoltage applied thereon.
- a conventional surge arrester comprises a resistor body (11), including a ceramic core (111) and a conductive film (112), the conductive film being deposited on the ceramic core entirely; two caps (13); an opening (14); a glass tube (15), sealing the resistor body, caps and opening; and neon gas, being filled inside the glass tube.
- the conventional surge arrester further provides two leads (161 and 162), each attaching to one of two ends of the glass tube and one of two discs (171 and 172), sealing the above elements.
- Such a conventional surge arrester is complex in construction and difficult in production, requires the same expansion coefficient for the glass tube and the two discs, and it thus is impractical in use.
- the industry thus needs an improved surge arrester which contains a simplified construction and has superior performance for absorbing transient voltages.
- the present invention relates to a surge arrester, comprising: a resistor body, including a ceramic core and a conductive film, the conductive film being deposited to enclose the ceramic core entirely; two caps, each enclosing one end of the resistor body; an opening, being cut in the middle part of the resistor body to separate the surface of the resistor body into two portions; a porous layer, filled in the opening; and an insulating layer, coated to protect the porous layer, the opening and the resister body.
- a surge arrester (30) comprises a resistor body (31), including a ceramic core (311) and a conductive film (312) of a metal film, a carbon film, a metal oxide film, or a metal glaze film, the conductive film being deposited to enclose the ceramic core entirely; two caps (33), each enclosing one end of the resistor body; an opening (34), being cut in the middle part of the resistor body to separate the surface of the resistor body into two portions; a porous layer (35), filled with ceramic particles, such as quartz sand, in the opening; and an insulating layer (36) of an epoxy resin, coated to enclose the porous layer, the resister body and the two caps (33).
- Each of leads (371 and 372) is provided on each of the caps (33), and the insulating layer (36) is coated to further enclose the caps.
- the surge arrester of the invention it is easy to produce the surge arrester of the invention using a production procedure similar to fabricating a traditional resistor. If an electronic device to be protected is easily subject to a transient voltage of 200 volts or 1000 volts or higher, the surge arrester of the invention will bypass such an overvoltage in an efficient and reliable way, thereby protecting the electronic device in a safe manner.
